A Practical example of controlling FPAG from HPS - FPGA SoC

First thing is understaning at high level what we are aimed to do.

We are going to use DDR3 Ram and map it as a common location that HPS (running linux) will write in memory location using a C program. FPGA looks into the same DDR3 Ram location. The memory is mapped to LEDs connected to FPGA. At the end, running a counter in C will light up LEDs.

How to design:

- We will use "Designer" to add IPs.

How to program:

• We will use JTAG to program FPGA
• We will generate header file listing the memory locations. Then we will write a C code to assign value based on a counter to the memory.

How to start:

Download the zip file. Open it in Quartus Prime.

you need linux loaded on HPS.

• Linux LXDE Desktop (kernel 4.5)
• Connect linux to internet
• Move HPS_FPGA_LED built from c file to linux that will run the counter.
• Program FPGA; MSEL[4:0] needs to be set to “01010” before the board is powered on.
• Run HPS_FPGA_LED in terminal
• You should see LEDs will light up on the counter running.
